Embodiment Construction

[0056] Figure 1A to Figure 1C A schematic diagram of a part of the thermal overload protection device 10 is shown. This part includes the switching element 12 for disconnecting the current-carrying element 16 from Figure 4 to Figure 9 The conductive connection 14 between the connection points 18 of the electrical component 20 is shown in the specific example embodiment. This part also includes an actuator device 22 and a trip element 24. The trip element 24 trips the actuator device 22 in a thermally sensitive manner. in Figure 1A to Figure 1C In the example shown, the trip element 24 is formed as a fusible element 26. This fusible element 26 is a soldered connection within the conductive connection 14, wherein the soldered connection enables current to flow through the connection 16 in the connected state.

[0057] Figure 1A Displays the conductive connection 16 when the switching element 12 and the actuator device 22 are in an inactive state. In the inactive state, the switc...

Abstract

A thermal overload protection arrangement for protection of an electrical component, which is arranged on a mount device having current-carrying elements, has a plurality of soldered connections, which make electrical contact between in each case on of the current-carrying elements and an associated connection of an electrical part and melt if the component is overloaded, and a disconnection apparatus for disconnection of at least one of these connections. The part is or at least has the component, and the disconnection apparatus is a disconnection apparatus which prestresses the component with respect to the mount device at least when it is heated for the physical separation of the component from at least one of the current-carrying elements, which trips when the soldered connections melt. The invention also relates to a corresponding method for protection of a component.

Description

Technical field [0001] The present invention relates to a thermal overload protection device. The thermal overload protection device is used to protect electrical components, especially electronic components. The thermal overload protection device includes: a switching element for short-circuiting the connection points of the components, Or used to disconnect the conductive connection between at least one of the connection points and the current-carrying element of the overload protection device; an actuator device used to switch the switching element to an appropriate short-circuit position or disconnect Position; and a tripping element for tripping the actuator device in a thermally sensitive manner. Background technique [0002] This type of overload protection device has been described, for example, in German Patent Publication DE102008022794Al. The document describes a thermal overload protection device, the thermal overload protection device includes: a short-circuit devic...
